problem creating asyncSocket in XP

Hi,
I am migration a program running on Nt to XP, in NT everything works fine,
but in XP the connect call fails with a weird error (183), i catch the error
and continue with the execution as if it returns a WSAEWOULDBLOCK, when i get
the message in Onconnet (response time expired, the ip i am connecting to is
not connected) i close the socket and try again, but the next time i do the
create it crash with the same error (183)... the weird thing is that the same
code is perfectly running on NT.
Anybody?
Thanks in advance
int CClisock::NCreaSocket()
{
    int nErr;

//creo el socket
    if (Create( /*PORT_NUM, SOCK_STREAM,
FD_READ|FD_WRITE|FD_CONNECT|FD_CLOSE*/) == 0)
    {
    m_bConnected = FALSE;
        m_bHaySock = FALSE;
        return -1;
    }

    //me intento conectar para mantener una conexion establecida
    if (Connect(m_sDirIp, PORT_NUM) == 0)
    {
        nErr = GetLastError();
        if (nErr != WSAEWOULDBLOCK)
        {
            m_pInfof->VInfof(INFO_ERR, "NCreaSocket Connect Err: %d", nErr);

            VCierraSocket();

            return -1;
        }
    }

    m_bHaySock = TRUE;

    return 1;
}
